atmosphere mostly consists of hydrogen, helium and methane
appears blue from the methane gas
Asteroid Belt
Asteroid Belt objects are made of rock and stone. Some are solid objects, while others are orbiting “rubble piles”.
The Asteroid Belt contains billions and billions of asteroids.
Some asteroids in the Belt are quite large, but most range in size down to pebbles.
Asteroids get their names from suggestions by their discoverers and are also given a number.
We know of at least 7,000 asteroids.
Thanks for watching my presentation about our solar system
It is 2-4 AU from the sun to the asteroid belt.
Kuiper Belt
The asteroid belt is the belt between the first four and the last four planets.
The Kuiper Belt is the belt behind all the planets.
it is between 30 and 50 AUs from the sun.
It is like the asteroid belt but much larger; 20 times as wide and 20 to 200 times as massive.
There is an estimated trillion or more comets within the Kuiper Belt.
Oort Cloud
made up of bodies of rock and ice
reaches between 5,000 and 100,000 astronomical units
contains around 0.1 to 2 trillion icy bodies
long period comets come from here
discovered by Dutch astronomer Jan Oort
A comet:
A celestial object consisting of a nucleus of ice and dust and, when near the sun, a ‘tail’ of gas and dust particles pointing away from the sun.

Short Period Comets:
A Comet that has orbital periods of less than 200 years and come from the region known as the Kuiper belt
Long Period Comets:
Comets that have periods greater than 200 years and come from the Oort cloud.
Most short period comets come from here.
Dwarf Planets:
A planetary-mass object that is not a planet nor a natural satellite but is in direct orbit of the sun and has enough gravity for its form to be hydrostatic equilibrium but not strong enough to clear a path for itself.
